Abstract
Systems and Methods for extracting concrete blocks or other materials cut from a surface is disclosed. An extraction apparatus typically includes a leveraging device connected to a vacuum cup and vacuum pump. The vacuum cup is placed on the material to be removed. A vacuum is pulled on the vacuum cup. The leveraging device is maneuvered to lift the material. The vacuum can be removed when the material is moved to the desired location.
